TABLE FUR BOX-NAILING MACHINES.

SPECIFICATION forming part of Letters Patent No. 561,692, dated June 9,1896. Application filed June 30, 1894. Serial No. 516,200. (No model.)

To all wham it may concern.-

Be it known that I, BENJAMIN S. A'rwoon, of \Vhitman, in the county ofPlymouth and State of Massachusetts, have invented certain new anduseful Improvements in Tables for Box-Nailing Machines, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

My invention relates to mechanism connected to the table of abox-nailing machine by which the said table, after being adjusted fornailing on one side of a box, may be dropped a certain distance equalingthe thickness of the second side to be nailed on, this distance beingregulated by an adjustingscrew controlled by the operator to make itconform to the thickness of the second side. This object I attain by themechanism shown in the accompanying drawings, in which Figure 1 is aperspective View showing parts of a boX-nailin g machine and table withmy adjusting device attached. Fig. 2 is an elevation showing a table andsuch parts of a boX-nailingmachine as are more nearly connected with it.Fig. 3 is an elevation showing details.

In the drawings, A represents a part of the body of an ordinaryboX-nailin g machine, and B the table, upon which the box is placedwhile being nailed.

K represents a bracket or framework adapted to be moved upward inrelation to the naildriving machinery. Upon the sides of the bracket Karefirmly attached projections C C, having inclines, as shown at 0 Fig.2. There are two or more of these projections upon each side of thebracket K. The table 13 is held in place by steady-pins E E, but is freeto be raised or lowered in relation to the bracket K.

The raising and lowering of the table in relation to the bracket K areeffected by means of sliding bars, one of which is shown at D. These twosliding bars are connected together by a rod D which serves as a handleby which the operator can move them both at once.

D and D are two wedge-shaped projections attached to the slidingbars Dand are adapted to operate in connection with the inclines on theprojections O C, so that when the rods D are drawn out, as shown inFigs. 1 and 3, the

table drops to its lowest position in relation to the bracket K, andwhen they are pushed in, as shown in Fig. 2, the table is raised up.

To adjust the table B for use the wedgebars D are pushed in, as shown inFig. d. Then the bracket K is raised in the usual manner until the tableB occupies the level required for nailing the side H onto the box, asshown in Fig. 2. The bracket remains stationary, but the table 13 maybelowered a limited distance by pulling out the slides D. This lastmovement of the table B should equal the thickness of the side H of thebox. (See Fig. 8.) This movement is limited to just the amount requiredby means of the screws S, which are adjusted to the exact height for thelowest position of the table B, and the nailing of the side H is done.To restore the table B to its height for beginning the nailing of a boxthe sliding rods D D are pushed in. This raises the table B to theheight required, as shown in Fig. 2.

I claim- In a box-nailing machine, the combination of the adjustablebrackets K K having attached to them, projections G C each of theprojections O 0 having limiting set-screws S S whereby the amount thatthe table is lowered is determined; with the slides D D each havingwedges D D and table B, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses on this 27th day of June, A. D.1894-.

BENJAMIN S. ATWOOD.
